EUGENE, Ore. - Senior second baseman Jackie Sweet was 4-for-6 at the plate with two doubles and an RBI, but the University of Utah softball team could not avoid a doubleheader sweep (11-3 in six innings and 11-1 in six innings) at No. 10/9 Oregon on Tuesday in Pac-12 Conference action at Howe Field.

Utah (14-18-1, 1-7 Pac-12) was led offensively on the day by four hits in six at-bats between both games for Sweet, who extended her hit streak to nine games. She cracked a leadoff single to left field in the fourth inning of game one and then proceeded to go 3-for-3 in the day's finale, including a run-scoring double to left-center field in the first inning and laced another double to right-center field in the sixth.

Sweet now has 14 RBI this season and 54 during her career. The Corona, Calif., native now has 31 career extra-base hits with eight coming this season. She has 11 multi-hit efforts in 2013.

Oregon got out to a fast start with eight runs in its first three at-bats before Utah was able to put three runs on the scoreboard in the fifth and sixth frames.

Sophomore Marissa Mendenhall went 3-for-3 with an RBI in game one against the Ducks. She has nine multi-hit games this year and also drove in her 16th run of the season.

Mendenhall led off the fifth with another base hit, this time to left field. Sophomore Shelbi Everett then followed by hitting into a fielder's choice that forced pinch runner Sandi Fawson out at second base. Freshman third baseman Stewart then connected on a base hit to right field to put Utes on first and second base. Junior center fielder Chalese Fankhauser converted on the RBI opportunity by hitting the third single in the frame to push Everett across home plate for Utah's first score of the contest. Stewart then scored on a wild pitch by Oregon pitcher Jessica Moore.

Freshman catcher Shelby Pacheco started Utah's two-out rally in the sixth with a single past the Oregon shortstop and Mendenhall's third and final hit of the game, a double off an 0-1 delivery through the left-center field gap, allowed Pacheco to score from first base.

Sophomore Mariah Ramirez made the start and threw 4.0 innings, but unfortunately saw her record fall to 4-7 in decisions this season. Junior Naomi Amu went 1.1 innings in relief.

Game 2: No. 10/9 Oregon 11, Utah 1 (6 inn.)

Sweet went 3-for-3 with a pair of doubles and RBI in the second game of the day, while sophomore Kate Dickman registered a double through the left-center field gap in the first inning for her 18th double of the season.

This time it was Utah who got off to the quick start Fankhauser led off the game by reaching second base after an errant throw by the Duck third baseman. Fankhauser then came around to score after Sweet slapped a double to left-center field. Sweet also doubled to right-center field in the fifth inning for her sixth double of the year and 18th of her career. Unfortunately, Oregon responded with 11 unanswered runs to capture the win in the second game of the day.

Amu turned in her seventh complete-game effort of the season in the second game of the twin bill. She yielded seven earned runs on 12 hits as her record unfortunately evened to 7-7 on the mound this season.
